Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. In particular, the following examples are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0019] please participate Figure 1 to Figure 3 , in one embodiment of the present invention, the SIM card base module for inserting a SIM card includes a substrate 10 , a limiting member 20 and a detection unit 30 . The picture also shows the SIM card placed into the SIM card base module.

[0020] The substrate 10 is provided with a circuit electrically connected to the SIM card, so that the operations of signal transmission and data reading and writing can be performed between the SIM card and the SIM card base module. Apparently, the circuit can be arranged inside the substrate 10 or on the surface of the substrate 10 , which is not limited here. The substrate 10 is also provided with a signal inpu...

Abstract

The embodiment of the invention discloses an SIM (Subscriber Identity Module) card base module for inserting an SIM card and a mobile communication terminal equipped with the SIM card base module. The SIM card base module comprises a base plate, a limiting piece and a detecting unit, wherein the base plate is provided with a circuit which is electrically connected with the SIM card and a signal input end for inputting signals; the limiting piece and the base plate are connected to form a clamping groove for containing the SIM card; the detecting unit is adjacent to the SIM card and is used for being in contact with the signal input end to generate a detection signal before the SIM card is pulled out; and read-write operation of the SIM card is stopped according to the detection signal. According to the embodiment of the invention, before the SIM card is taken out, the detection signal is sent to the signal input end of the base plate by the detection unit to stop the read-write operation on the SIM card, so that the condition that the SIM card is burnt out when the SIM card is taken out is avoided.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile communication terminal and a SIM card base module thereof. Background technique [0002] In the prior art, for mobile phones and other terminal devices that require a SIM (Subscriber Identity Module, customer identification module) card, in order to achieve the effect of light and thin, the SIM card and the battery are generally set separately, instead of the SIM card It is sandwiched between the battery and the SIM card base module, that is to say, the user can directly take out the SIM card without taking out the battery first. Since there is no need to take out the battery, the mobile phone is in a power-on state or in a working state. At this time, there may be read and write operations between the mobile phone and the SIM card. Obviously, if you take out the SIM card when there is still a data transmission operation between the mobile phone and the SIM card, it ...
